Hi again,
Ok I seem to be having never ending problems here unfortunately. Using this
code (below) I thought I could modify it for my needs. But on the
FSPathMakeRef line I keep getting the warning that "pointer targets in passing
argument 1 of 'FSPathMakeRef' differ in signedness." Would someone mind
telling me why I'm getting this error? Thanks you very much!
- (NSDate *)creationDate:(NSString *)path
{
FSRef ref;
FSCatalogInfo catalogInfo;
OSStatus status;
OSErr err;
NSTimeInterval seconds;
NSCalendarDate *epoch = [NSCalendarDate dateWithYear:1904 month:1
day:1 hour:0 minute:0 second:0 timeZone:[NSTimeZone
timeZoneForSecondsFromGMT:0]];
status = FSPathMakeRef([path fileSystemRepresentation], &ref, nil);
if (status != noErr) {
NSLog(@"error making ref for %@: %d", path, status);
return nil;
}
err = FSGetCatalogInfo(&ref, kFSCatInfoCreateDate, &catalogInfo,
NULL, NULL, NULL);
if (err != noErr) {
NSLog(@"error getting catalog info: %d", err);
return nil;
}
seconds = (double)((unsigned long
long)catalogInfo.createDate.highSeconds << 32) +
(double)catalogInfo.createDate.lowSeconds +
(double)catalogInfo.createDate.fraction / 0xffff;
return [epoch addTimeInterval:seconds];
}
